Are They Worth the Money?

Superfruit is a word that you are going to hear more often. It’s
very similar to a superfood except for the focus is on fruit specifically.
Along with blueberries and cranberries, three of the hottest fruits in
the superfruit arena right now are pomegranate, the acai berry, and mangosteen.
Are they really disease busters or are they just alternatives to orange
juice that are nutritious and expensive?
The potential health benefit of superfruits focuses on the antioxidant
content. Antioxidants include vitamin C and E for example but also the
naturally occurring plant chemicals in the fruit called phytochemicals
(phyto meaning plant). Just because a superfruit has a high antioxidant
content, does this mean it automatically translates into a health benefit
in the human body? The only way to know for sure is to conduct nutrition
research and test whether these antioxidants can destroy free radicals
in humans and whether this cell destruction lowers the risk of disease
and helps versus hinders something like inflammation.
Pomegranates are hot right now. You can find pomegranate in everything
from juice and nutrition bars to cereals, smoothies and tea. Pomegranate
juice costs three-four times more than orange juice and has almost twice
the calories per serving. Preliminary studies have been done and further
long term studies are in the works. These preliminary studies show the
potential benefit of pomegranates in helping to prevent prostate cancer.
Preliminary data also points to potential benefits for the heart in terms
of improving blood flood thru the arteries. Pomegranates rank right up
there with blueberries and strawberries when it comes to antioxidant levels.
What about mangosteen juice? It comes from the fruit of the mangosteen
tree native to Southeast Asia. It’s not related to the mango although
it sounds like it. Currently, mangosteen juice is heavily marketed thru
multi-level marketing and Internet sites which boast strong claims to
its health benefits. You’ll find hyped benefits promising help to
cure cancer and diabetes, migraines and many other diseases.
Is mangosteen a good source of antioxidants? Yes. Has it been shown to
cure disease or even help prevent cancer and other diseases in humans
to date? No. The American Cancer Society on their website contends while
mangosteen juice is a source of antioxidants, there is no reliable evidence
for its use as a cancer treatment. In fact the FDA sent out a warning
letter to one mangosteen company in 2006 for marketing the product to
treat illness for which there is no proof.
Another superfruit that you’re hearing more about are acai berries
from Brazil (pronounced ah-SAH-ee). You can find acai berries incorporated
into juice, cereals, smoothies and more. The berries are a source of phytochemicals
called flavonoids These are the same ones you’ve heard about in
chocolate and wine. A study from the University of Florida found that
compounds in acai berries could reduce growth of certain leukemia cells
in the lab. This preliminary data now needs to be confirmed through human
studies. Other research in the lab and on animals shows the potential
for an anti-inflammatory effect. Again, human studies need to be done.
Pomegranate, mangosteen juice and acai berries are all superfruits in
that they are good sources of antioxidants and can be part of a healthy
diet rich in fruits and vegetables. To date, research on the benefits
in humans has not been conducted or else is very limited to back up the
myriad of promises you’ll find associated with these products. They
can be very expensive costing up to $70-80 a bottle and are not miracle
cures as often promised. Always do a reality check when a product promises
to treat/cure all types of diseases.
